IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2,
3 and 4, please read and observe the following:
Power Supply
301
Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
307
Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
308
Although the LCD and LEDs are switched off when the
POWER switch is switched off, this does not mean that the
unit has been completely disconnected from the source of
power. If you need to turn off the power completely, first
turn off the POWER switch, then unplug the power cord
from the power outlet. For this reason, the outlet into
which you choose to connect the power cord’s plug
should be one that is within easy reach.
Placement
351
Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter-
ference.
352a
This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
352b
Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initi-
ating a call, or while conversing. Should you experience
such problems, you should relocate such wireless devices
so they are at a greater distance from this unit, or switch
them off.
353
Observe the following when using the unit’s floppy disk
drive. For further details, refer to “Before Using Floppy
Disks” (p. 6).
Do not place the unit near devices that produce a
strong magnetic field (e.g., loudspeakers).
Install the unit on a solid, level surface.
Do not move the unit or subject it to vibration while
the drive is operating.
354b
Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Also, do not allow lighting devices that normally are used
while their light source is very close to the unit (such as a
piano light), or powerful spotlights to shine upon the
same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.
355
To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
356
Do not allow rubber, vinyl, or similar materials to remain
on the unit for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
358
Do not allow objects to remain on top of the keyboard.
This can be the cause of malfunction, such as keys ceasing
to produce sound.
359
Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.
Maintenance
401b
To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.
402
Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
The pedals of this unit are made of brass.
Brass eventually darkens as the result of the natural
oxidization process. If the brass becomes tarnished, polish
it using commercially available metal polisher.
For KR-5-PE
Since your piano has a polished finish that is as delicate as
that found on finely crafted wooden furniture, it needs
careful, periodic care. A few important suggestions
concerning the proper care of the unit follow.
For dusting, wipe the instrument with a soft cloth
that has been soaked with water, then squeezed dry.
Be sure to wipe gently. Even the tiniest grains of sand
or grit can leave scratches on the surface if too much
force is applied while wiping.
Do not use any cleaners or detergents, since they might
deteriorate the surface of the cabinet, and produce
cracks. Do not use dusting cloths that contain
chemicals.
Additional Precautions
551
Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have stored in the unit’s memory on a floppy disk.
552
Unfortunately, it may be impossible to restore the contents
of data that was stored on a floppy disk once it has been
lost. Roland Corporation assumes no liability concerning
such loss of data.
553
Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
554
Never strike or apply strong pressure to the display.
556
When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
557
•A small amount of heat will radiate from the unit during
normal operation.
